Abstract

Background

The use of statistical parameter mapping (SPM) to compare gait kinematics of children at different ages seems to be a more appropriate tool to describe the differences than simply describing the maxima and minima on the curves.

Research question

Does lower limb kinematic waveforms differ during gait in normally developing preschool children?

Methods

In a cross-sectional study, SPM was used to compare kinematic waveforms of typically developing preschool children at ages 2, 3, and 6 years (n = 42).

Results

Differences in internal rotation foot angle between 2-year-olds and 3-, 6-year-olds in 22–55 % lower in 2-year-olds but 85–100 % greater in 2-year-olds. Greater internal rotation of the knee in 2-year-olds versus 6-year-olds in 13–25 % of the stance phase. Lower knee abduction in 2-year-olds versus 6-year-olds in the first 13 % of the stance phase.

Significance

Comparison of the waveforms of the angle may provide a clearer understanding of the differences in gait kinematics in children at different ages.

背景使用统计参数图谱（SPM）比较不同年龄儿童的步态运动学似乎比简单描述曲线上的最大值和最小值更适合描述差异。方法在一项横断面研究中，使用 SPM 对 2、3 和 6 岁发育正常的学龄前儿童（n = 42）的运动波形进行比较。结果2 岁儿童和 3、6 岁儿童的足内旋角差异为：2 岁儿童低 22-55%，但 2 岁儿童高 85-100%。在 13-25% 的站立阶段，2 岁儿童的膝关节内旋角度大于 6 岁儿童。在站立阶段的前 13%，2 岁儿童的膝外展比 6 岁儿童的低。

期刊介绍： Gait & Posture is a vehicle for the publication of up-to-date basic and clinical research on all aspects of locomotion and balance. The topics covered include: Techniques for the measurement of gait and posture, and the standardization of results presentation; Studies of normal and pathological gait; Treatment of gait and postural abnormalities; Biomechanical and theoretical approaches to gait and posture; Mathematical models of joint and muscle mechanics; Neurological and musculoskeletal function in gait and posture; The evolution of upright posture and bipedal locomotion; Adaptations of carrying loads, walking on uneven surfaces, climbing stairs etc; spinal biomechanics only if they are directly related to gait and/or posture and are of general interest to our readers; The effect of aging and development on gait and posture; Psychological and cultural aspects of gait; Patient education.
